My Back Sweats a Lot

My Back Sweats a Lot

After speaking with a lady recently who says that her back sweats all the time and wanted to know how to cure a sweaty back, I thought I’d push a post through on this and see if this would help. The details of her case are similar to many but rather than just look at her individual case we will take a look at all possible cases.

Why Does My Back Sweat?

A sweaty back can be an indicator and another sign of hyperhidrosis, which affects huge numbers of people, so you’re not alone. Primary hyperhidrosis plays out through overactive sweat glands from a highly active sympathetic nervous system. If you find that you only have a sweaty back under certain conditions, like in bed or while sat on the sofa, there could be some of the other factors involved. Who doesn’t sweat if sat with bare skin on a leather (or ‘pleather’) sofa?

This then could well be secondary hyperhidrosis caused, as the name suggests, by secondary factors including the amount of coffee you drink, the clothes you wear, the types of food you eat and like almost everything else, smoking can also be a contributor. To decide what is causing it you are always advised to get proper diagnosis from your physician.


Most people only think of applying antiperspirant to their underarms, but you can certainly use it on your back if this helps to solve the problem. Other people I’ve spoken to have used clinical strength antiperspirants. This is going to get a little technical but after all the chemical compound speak, it just boils down to it being more effective than your standard antiperspirant.

In general these clinical grade antiperspirants contain things like aluminum chloride and aluminum chlorohydrate, which are just the active ingredients. As if those weren’t enough of a mouthful recently aluminum zirconium tetrachlorohydrex glycine has become a popular active ingredient. I understand that in the US you can buy over-the-counter antiperspirants that consist of between 15 and 25 percent aluminum – depending on the particular compound.


Wearing man made fibres that don’t wick the sweat away or irritate the sweat glands can be a cause of the excessive sweating. Wearing loose clothing and natural fibres is recommended in conjunction with the thin layer of antiperspirant advised above.

Diet and Lifestyle

The types of food and drink you consume can have a huge effect on the amount you sweat. Coffee for example contains caffeine, which is known to stimulate sweat glands can be a contributing factor. Beer and curry are renowned for causing sweats without any medical explanation from me! Leading a healthy lifestyle, including moderate exercise and a balanced diet can reduce sweating pretty quickly.

What if None of This Works?


Of course these simple steps aren’t going to cure all back sweats as some people are primary hyperhidrosis sufferers and may require further investigation. These could be looking at oral medication in conjunction with medical grade antiperspirants, or even Botox injections.

I hope this is of some use to people, and if you wish to ask anything don’t forget you can leave a comment or email me on
